High temperature resistant telescopic air duct, special air duct for positive and negative pressure ventilation of blower exhaust fan equipment
High temperature resistant telescopic air duct is a ventilation hose dedicated to exhaust air equipment. It can be connected to the fan for air extraction or exhaust. According to the pressure of the fan, the negative pressure resistant air duct for air extraction can be customized. The air duct used for ventilation and exhaust is the positive-pressure-resistant duct, and the exhaust duct connected to the fan to draw outward is the negative-air duct. However, whether it is a positive pressure duct or a negative pressure duct, the production materials and structure of the two are basically The same, the difference is the thickness of the ventilation hose cloth and the thickness and spacing of the steel wire.
One of the most commonly used positive and negative pressure resistant ventilation pipes on the market, such as high temperature resistant telescopic air pipe LKE400
Structure: Patented CP structure (CP is the abbreviation of clamp profile), special glass fiber coating, external spiral, galvanized steel clip (steel sheet with anti-wear plastic); Patent number: ZL201130194610.7, super strong Resistance to positive and negative pressure.
Performance: good vacuum characteristics, the external spiral galvanized sheet has very good wear resistance, dragging on the ground will not damage the air duct, flexible, arbitrary expansion and bending, flame retardant, insulation, high temperature resistance, shock resistance Dynamic, strong toughness and chemical resistance.
Production diameter: 1 inch -50 inch The bending radius is about larger than the radius, the expansion ratio: 5:1;
